Caramelised onions is one of my favourite ingredients. I love caramel at any time, and onions are the basis for so many dishes, however they have been prepared. That’s why I added them to my sausage rolls. Of course you can buy them in a jar, but making them usually gives better results.
Recipe for Caramelised Onions
3 red onions
1 white onion
dash of olive oil
3 tbsps brown sugar
50 ml warm water
1 tsp balsamic vinegar
Thinly slice the onions and fry gently with the butter and olive oil until they are soft and translucent. It’s very important to let them cook slowly – if they burn the bitterness will come out, which will spoil the sweetness.
When the onions are soft and translucent and just starting to brown, add the brown sugar, balsamic vinegar and a splash of water and stir well. Then cover the pan and cook on a low heat for 15 minutes, stirring once or twice only, to ensure it doesn’t stick.
After 15 minutes, check the onions to see how much moisture is left. The less moisture there is, the sweeter and stronger the caramel flavour will be. Cook the onions in the same way – on a low heat with the lid on – until you get the consitency you want. For the sausage rolls recipe you will need the least amount of moisture, so they look like the onions below.
When the onions are caramelised to your liking, use immediately or store in the fridge for up to a week.
